Pengembangan E-LKPD Liveworksheets Berorientasi Model Pembelajaran Kooperatif Think Pair Share untuk Melatihkan Keterampilan Berpikir Kritis Peserta Didik pada Materi Asam Basa

Development of Cooperative Learning Think Pair Share Oriented e-Worksheet to Improve Critical Thinking Skills Students on Acid-Base Material

Penelitian ini bertujuan untuk memperoleh E-LKPD berorientasi model pembelajaran kooperatif Think Pair Share untuk meningkatkan keterampilan berpikir kritis peserta didik pada materi asam basa sebagai bahan ajar yang layak digunakan. Kelayakan E-LKPD meliputi validitas, kepraktisan, dan keefektifan. Jenis penelitian yang digunakan adalah R&D dengan model 4-D, namun pada penelitian ini hanya dibatasi hingga tahap develop. Hasil penelitian menunjukkan validitas isi dan validitas konstruk E-LKPD mendapatkan kriteria valid. Kepraktisan mendapat kriteria sangat praktis ditinjau dari hasil angket respon peserta didik sebesar 97% dan didukung dengan hasil observasi aktivitas peserta didik dengan hasil 95% aktivitas yang relevan. Keefektifan ditinjau dari hasil uji paired sample t-test dengan nilai p-value 0.00, p-value <0.05 yang artinya terdapat perbedaan yang signifikan antara pretest dan posttest kemampuan berpikir kritis peserta didik. Berdasarkan hal tersebut menunjukkan bahwa E-LKPD yang dikembangkan efektif. 

This research aims to obtain a cooperative learning Think Pair Share model oriented e-worksheet to improve students' critical thinking skills on acid-base materials as teaching materials that are feasible to use. E-Worksheet qualifications cover validity, practicality, and effectiveness. The type of research used is R&D with the 4-D model, but in this research, it is only limited to the develop stage. The research results showed the validity of the contents and validity of e-Worksheet construction obtained valid criteria. Practicality received very practical criteria based on the results of the student response questionnaire of 97% and supported by the results of student activity observations with 95% of relevant activities. Effectiveness is reviewed from the results of the paired sample t-test with a p-value of 0.00, p-value <0.05 which means there is a significant difference between the pretest and posttest of students' critical thinking skills. Based on this, it shows that the e-Worksheet developed is effective.
